In page Broncho Billy Anderson:

"

In 1907 in Chicago, Anderson and George Kirke Spoor founded Essanay Studios ("S and A" for Spoor and Anderson), one of the major early movie studios. In 1909, he directed the film with the first known instance of the pie-the-face gag, Mr. Flip. Anderson acted in over 300 short films. He played a wide variety of characters, but he gained enormous popularity from a series of 148 silent western shorts and was the first film cowboy star, "Broncho Billy."[2] Many of these were shot in Niles,[1] a small town in Alameda County, California, south-east of San Francisco, where the nearby Western Pacific Railroad route through Niles Canyon proved to be a very suitable location for the filming of Westerns.[citation needed]
